If it is a 930, retard the timing and reduce the boost with a .6 or .5 Bar spring, or lay off the throttle. Personally, I find it hard to lay off the throttle on a 930. I always say Absolute power corrupts absolutely.

There goes that priest in that 930, what an Azzhole!!

You get the idea.

My wife has a Mercedes, that takes 93 Octane, just suck it up and buy 93 Octane. Your only other option is to retard the timing a couple degrees.

EDIT: I may have mis-read this. Are you saying that 93 Octane is unavailable to you?
